D (Delta) channel: 16 kbpsD-channel takes care of call set-up, call control (call forwarding, call waiting, etc.), and maintenanceControl and maintenance can be done in real-time in D-channel while B-channel is still transmitting data-big elk!
yes, we can but we need terminal adapter to connect with ISDN if ordinary line is used . terminal adapter use to convert non ISDN to ISDN.

Here are some differences between broadband ISDN and narrowband ISDN: 1) Narrowband ISDN uses 64 kb/s channel, while broadband ISDN uses 100 mb/s channels. 2) Broadband uses call relay, while narrowband uses frame relay. 3) In narrowband, ISDN information carries narrow frequency, while in broadband, ISDN uses a wide band of frequency.
ISDN lines are mainly used for phone usage. It replaces the analog phone that is found in most homes. It has the ability to take just the one phone line, and turn it into two lines.

64 kbps is typically a low-speed internet connection, considered to be part of the dial-up category. It is relatively slow by today's standards and is commonly used for basic online activities such as sending emails or basic web browsing.
